The prophylactic use of negative-pressure wound therapy after cardiac surgery: a meta-analysis

Surgical site infections (SSIs) pose a frequent complication in cardiac surgery patients and lead to increased patient discomfort and extended hospitalization. This meta-analysis aimed to evaluate the protective role of single-use negative-pressure wound therapy (sNPWT) devices on closed surgical wounds after cardiac surgery, and explored their potential preventive application across all cardiac surgery patients. A comprehensive literature search was conducted on ScienceDirect, focusing on studies related to "negative pressure wound therapy" or "PICO negative pressure wound therapy" combined with "cardiac surgery" or "sternotomy," published between 2000 and 2022. Inclusion criteria encompassed case-control studies comparing sNPWT with traditional dressings on closed cardiac surgical incisions in adult patients undergoing median sternotomy without immediate postoperative infective complications, with available details on SSIs. A retrospective analysis of cases treated with sNPWT in our centre was also performed. The meta-analysis revealed a protective role of sNPWT, indicating a 44% risk reduction in overall SSIs (odds ratio 0.56) and a 40% risk reduction in deep wound infections (odds ratio 0.60). Superficial wound infections, however, showed non-significant protective effects. A single-centre study aligned with the meta-analysis findings, confirming the efficacy of sNPWT and was included in the meta-analysis. In conclusion, the meta-analysis and the single-centre study collectively support the protective role of negative pressure wound therapy against overall and deep SSIs, suggesting its potential prophylactic use on all cardiac surgery populations.

A systematic review and meta-analysis of germline BRCA mutations in pancreatic cancer patients identifies global and racial disparities in access to genetic testing

BACKGROUND

Germline BRCA1 and BRCA2 mutations (gBRCAm) can inform pancreatic cancer (PC) risk and treatment but most of the available information is derived from white patients. The ethnic and geographic variability of gBRCAm prevalence and of germline BRCA (gBRCA) testing uptake in PC globally is largely unknown.

MATERIALS AND METHODS

We carried out a systematic review and prevalence meta-analysis of gBRCA testing and gBRCAm prevalence in PC patients stratified by ethnicity. The main outcome was the distribution of gBRCA testing uptake across diverse populations worldwide. Secondary outcomes included: geographic distribution of gBRCA testing uptake, temporal analysis of gBRCA testing uptake in ethnic groups, and pooled proportion of gBRCAm stratified by ethnicity. The study is listed under PROSPERO registration number #CRD42022311769.

RESULTS

A total of 51 studies with 16 621 patients were included. Twelve of the studies (23.5%) enrolled white patients only, 10 Asians only (19.6%), and 29 (56.9%) included mixed populations. The pooled prevalence of white, Asian, African American, and Hispanic patients tested per study was 88.7%, 34.8%, 3.6%, and 5.2%, respectively. The majority of included studies were from high-income countries (HICs) (64; 91.2%). Temporal analysis showed a significant increase only in white and Asians patients tested from 2000 to present (P < 0.001). The pooled prevalence of gBRCAm was: 3.3% in white, 1.7% in Asian, and negligible (<0.3%) in African American and Hispanic patients.

CONCLUSIONS

Data on gBRCA testing and gBRCAm in PC derive mostly from white patients and from HICs. This limits the interpretation of gBRCAm for treating PC across diverse populations and implies substantial global and racial disparities in access to BRCA testing in PC.

Communication on analgesia and sedation: parents’ opinions in six pediatric ICU in northern Italy

Introduction

Communication between healthcare professionals and parents regarding analgesic and sedative treatments for seriously ill children is challenging. Although appropriate information may help parents during admission to the pediatric intensive care unit (PICU), some areas of communication may be missed.

Objectives

To explore and describe the opinions of parents of children admitted to PICU about analgosedation, information received about it and its potential adverse effects, and suggestions for improving the comfort of hospitalized children.

Methods

Parents’ opinions were collected in six PICUs in northern Italy. Parents of children who were hospitalized for more than 48 hours and required analgesia and sedation were asked to provide opinions on the quality of information with respect to the treatments used, possible short- and long-term sequelae, satisfaction with efficacy, environmental factors perceived as disturbing, and suggestions for improving children’s comfort.

Results

Forty-eight parents participated. Information about analgosedation was rated, as was its effectiveness. Parents pointed out some interesting suggestions to improve their children’s comfort during their hospitalization in PICU. On the other hand, it was found that information about possible complications, withdrawal syndrome, delirium, or difficulties in obtaining the desired level of sedation was often provided poorly or inadequately. In addition, wide differences were found between centres, particularly with regard to analgosedation side effects and withdrawal syndrome.

Conclusions

Parents should receive early explanations of these potential complications. Even considering the limited number of participating PICUs, distributed exclusively in northern Italy, and the small number of participants, this is the first data collection focused on communication between health professionals and parents of children undergoing analgosedation treatment in pediatric intensive care units.

Key messages

• This is the first data collection focused on communication between health professionals and parents of children undergoing analgosedation treatment in pediatric intensive care units.

• Information about possible complications, withdrawal syndrome, delirium, or difficulties in obtaining the desired level of sedation was often provided poorly or inadequately.

Parents’ knowledge about their children’s congenital heart disease: an observational study

Introduction

Congenital heart diseases (CHD) represent abnormalities of cardiovascular structure or function present at birth. The degree of knowledge of parents of children with CHD determines the quality of care and the quality of life of their children. Several studies have shown that parents’ knowledge is still lacking.

Objectives

This study aims to translate and validate in Italian the Leuven Knowledge Questionnaire for Congenital Heart Disease (LKQCHD) and to assess the knowledge of parents of children with CHD about heart defect, treatments, preventive measures, opportunities for physical activity and reproductive problems of their children.

Methods

Translation and validation of the questionnaire were performed using a multistep method: forward translation, backward translation, and pilot testing. Five experts in CHD were included for the validation of the questionnaire. The sample consisted of fifty-four pairs of parents of children with CHD. Parents were contacted by telephone; knowledge was assessed using an electronic questionnaire.

Results

Five items were found to have an Item Content Validity Index (I-CVI) of 0.6, 2 of 0.5, and 2 of 0.2. The Scale ContentValidity Index (S-CVI) was found to be 0.80. Regarding parental knowledge, the results show that almost all parents are able to correctly state the name of the diagnosis and the description and location of the heart defect. However, parental knowledge has important gaps; in particular, parents are less informed about the most characteristic sign of endocarditis, the possibility of contracting endocarditis more than once in a lifetime, and risk factors. Parental knowledge also seems to be lacking regarding symptoms suggesting worsening health status in their children.

Conclusions

The Italian version of the LKQCHD has proved to be a valid tool to measure the level of knowledge of parents of children with CHD, allowing to identify in which areas it is necessary to improve the education addressed to parents.

Key messages

• Assessing the knowledge of parents of children with CHD allows to improve their education.

• The Italian version of the LKQCHD is a valid tool to measure the level of knowledge of parents of children with CHD.

Acute idiopathic pericarditis: the importance of guideline-based treatment to avoid recurrence

Background

Acute pericarditis (AP) usually resolves with first-line treatment, but it may recur. Recurrences are attributed to a deranged immunity, but it is unclear if they may also be related to inappropriate treatment.

Purpose

The aim of our study was to clarify the potential role of inappropriate treatment on relapse episodes in AP.

Methods

Consecutive patients prospectively followed-up over 20 years at Padua University Cardio-immunology outpatient clinic were included. Clinical and instrumental findings were recorded at diagnosis and at each follow-up. Spectrum, appropriateness, efficacy and side effects of therapies received by patients before and after referral to our centre were considered. The distribution of recurrence-free survival probability was estimated using Kaplan-Meier method; impact of the covariates of interest on the outcome was assessed using Cox univariate analysis models.

Results

The study included 144 patients (57% male, mean age 50 years, 143 Caucasian and 1 African). 139 patients had AP, which was recurrent in 63; 5 had constrictive pericarditis. Etiology was idiopathic/presumed-viral in 112 patients, bacterial in 1, secondary to pericardial injury in 26, to Dressler syndrome in 2, and to a systemic immune-mediated disease in 3. At diagnosis, 68% were in NYHA class I; 9% developed cardiac tamponade; 84% received non-steroidal-anti-inflammatory drugs (NSAIDs), 54% colchicine and 19% corticosteroids. Treatment was not in line with ESC guidelines in 31% of patients for NSAIDs, in 12% for steroids and in 28% for colchicine, requiring readjustment. All patients with constrictive pericarditis underwent uncomplicated pericardiectomy. No patient was dead at last follow-up. Estimated recurrence-free-survival probability was 86% at 1st year, 58% at 5th, 52% at 10th. Variables which tended to be associated with a higher risk of recurrence were: cardiac tamponade at diagnosis, left heart failure, concomitant immune-mediated diseases, history of recurrence, inappropriate treatment with colchicine, inappropriate treatment with NSAIDs, III or IV NYHA class at diagnosis. Treatment of acute/recurrent forms before referral did not appear in line with the international recommendations in terms of daily dosage or duration, or both, in 43 patients for NSAIDs, in 17 for corticosteroids and in 39 for colchicine, which was omitted despite the absence of contraindications (Table 1). Following treatment adjustment to international guidelines, 107 patients with relapsing pericarditis obtained complete remission; only 13 (9%) of our AP patients showed a truly treatment-refractory form that required a second-line therapy.

Conclusion

When treated according to international guidelines, pericarditis has usually a favorable course, even in its most adverse presentations. Treatment inaccuracies seems to account, at least in part, to disease recurrences.

Machine-learning algorithms for prediction of survival by stress echocardiography in chronic coronary syndromes

Background

Stress echocardiography (SE) is based on regional wall motion abnormalities and coronary flow velocity reserve (CFVR). They recognise different and complementary pathophysiological targets, and show independent and incremental value in predicting survival [1]. The approach based on machine-learning (ML) has the recognised potential to identify unsuspected patterns, and this can be especially relevant in the field of risk stratification by cardiac functional stress testing due to multiple parameters used in comprehensive stress testing and the variable weight of covariates [2].

Aim

To assess SE outcome data analysis with ML approach.

Methods

We included 6,881 prospectively recruited and retrospectively analyzed patients (median age 67 years, IQR 59–74) with suspected (n=4,279) or known (n=2,602) coronary artery disease submitted to clinically-driven dipyridamole SE in 5 Italian institutions (Figure 1). The primary outcome measure was all-cause death. A Random Forest Survival model has been implemented to model the survival function according to the patient's characteristics. The Random Forest predicted response dependency on covariates has been investigated by reporting the variable dependence and the partial dependency plot (Figure 2). A web application was developed to predict the survival function according to the patients' characteristics. The external validation cohort was made of additional 1,002 patients recruited by a single, independent center in the same time period.

Results

During a median duration of follow-up of 3.4 years (IQR 1.6–7.5), 814 (12%) patients died. The mortality risk was higher for patients aged more than 60 years, resting ejection fraction &lt;60%, resting WMSI, positive delta WMSI scores, and CFVR &lt;3.0. The C-index performance (perfect prediction=1) was 0.79 in the internal validation cohort and 0.81 in the external, independent validation data set. Survival functions for individual patient were easily obtained with an open-access web-app.

Conclusion

An ML approach can be fruitfully applied to outcome data obtained with SE. Survival showed a constantly increasing relationship between survival and CFVR &lt;3.0 and stress-rest wall motion score index &gt;0. Since processing is largely automated, this approach can be easily scaled to larger and more comprehensive data sets to further refine stratification, guide therapy and be ultimately adopted as an open-source on-line decision tool.

Adverse events prediction in nonischemic dilated cardiomyopathy by two machine learning models integrating clinical and cardiovascular magnetic resonance data

Funding Acknowledgements

Type of funding sources: None.

Background

Risk stratification of patients with nonischemic dilated cardiomyopathy (NIDCM) is challenging. Machine learning (ML) models represent novel technologic tools that promise to improve predictive ability of cardiovascular adverse outcomes.

Purpose

To implement two ML models to predict the risk of adverse outcome (composite endpoint of all-cause death, heart transplantation, implantation of ventricular assistant device), in patients with NIDCM using clinical and radiological data.

Methods

We retrospective collected data from patients affected by NIDCM referred to our cardiologic unit between 2002 and 2018. Two ML models, an extreme gradient boosting machine (XGBoost) and an artificial neural network (ANN), were developed using cardiovascular magnetic resonance (CMR) and clinical parameters. Both models were trained on 67% of patients and evaluated based on the other 33% as internal validation. To investigate the contribution of different features in our models, we used Shapley additive explanations (SHAP) analysis.

Results

The final cohort resulted of 161 patients (mean age 48.9±13.6 years, 71% males), with a mean follow up duration of 79.1 months. During the follow-up 29 adverse event were observed (16 deaths, 12 heart transplantation, 1 implantation of ventricular assistant device). ANN model resulted in an accuracy of 76% with an area under the receiver operating characteristic (ROC) curve of 0.66; SHAP analysis identified male sex, percentage of late gadolinium enhancement (LGE) and LGE distribution in the lateral wall of myocardium as the main markers of adverse outcomes. XGBoost model resulted in an accuracy of 78% with a ROC curve of 0.76; SHAP analysis identified NT-proBNP level, age and serum creatinine mainly related with adverse outcomes. About CMR parameters, left ventricular diameter and ejection fraction better related with adverse outcomes.

Conclusions

Our models achieved a good performance in prediction of adverse events, suggesting that ML could improve our ability of risk stratification of NIDCM. XGBoost better performed than ANN, and SHAP analysis suggested that both CMR parameters and clinical parameters contribute to the definition of risk.

POS0163 USEFULNESS OF WEARABLE DEVICES TO ASSESS PHYSICAL ACTIVITY IN NON-INFLAMMATORY AND INFLAMMATORY RHEUMATIC DISEASES: A SYSTEMATIC REVIEW AND META-ANALYSIS

Background

In the last years, the rise of personalized medicine has grown up. So, patient-oriented wearable technologies have been developed. Wearable devices (WD) are useful to collect objective data related to physical activity. In the management of rheumatic musculoskeletal disorders (RMDs) a regular physical activity is an important recognized non-pharmacological intervention [1].

Objectives

This systematic review aims at evaluating how the use of WDs impacts physical activity in patients with non-inflammatory and inflammatory rheumatic diseases.

Methods

A systematic review and meta-analysis were performed. A comprehensive search of articles was performed in the following databases: MEDLINE via PubMed, EMBASE, CINAHL, and Scopus. A random-effect meta-analysis has been carried out on the number of steps and moderate to vigorous physical activity (MVPA). Univariable meta-regression models have been computed to assess the possibility that the study characteristics may act as effect modifiers on the final meta-analysis estimate. The primary outcome is the level of physical activity evaluated with a wearable device as a number of daily steps and MVPA. The secondary outcome is the comparison of both a number of steps and MVPA to reference value for healthy people. The number of steps per day and the time spent in MVPA considered as a mean or median were collected. Missing information was calculated from available data when possible.

The reference value for steps was 7000 steps per day, this value was derived by a literature review commissioned by the Public Health Agency of Canada on the number of steps/day suitable for adults [2]. MVPA reference value was of 150 min/week and was derived by WHO guidelines [3].

Results

An overall of 1788 studies was considered in the title/abstract screening. In the analysis, 51 articles were included, with an overall of 7488 participants. Twenty-two studies considered MVPA outcome alone, 16 studies number of steps alone and 13 studies reported information on both outcomes.

The results of this meta-analysis show that there is a high level of I2 heterogeneity, 99%, according to diagnosis.

Recommended threshold for daily steps was reached for MVPA (36.35, 95% CI 29.39 - 43.31) but not for daily steps (-1092.60, 95% CI -1640.42 - -544.77), with fibromyalgia reporting a higher number (6290, 95% CI 5198.65 – 7381.62) of daily steps compared to other RMDs. Patients affected by chronic inflammatory arthropathies seem to fare better in terms of daily steps than the other categories. Patients with rheumatoid or other chronic arthritis reported a higher number of steps, respectively 6361 (95% CI 5382.51; 7340.35) and 6290.14 (95% CI 5198.65; 7381.62).

Non-elderly people show a higher overall level of physical activity compared to the elderly, 6796.11 (95% CI 5974.10; 7618.13) versus 5431.85 (95% CI 4633.76; 6229.95).

Non-elderly group show higher level MVPA compared to the reference value 38.96 (95% CI 18.35; 59.68) vs 11.77 (95% CI 3.32; 20.21).

Conclusion

RMDs suffer of low level of physical activity and WDs are useful and affordable instruments to support the increase of it. WDs can be used in daily monitoring of physical activity in RMDs.

Validation of a Nomogram to Predict Long Term Outcomes After Curative Surgery for Gastric Cancer in an Italian Cohort of Patients

AIM OF THE STUDY

Nomograms have been proposed to assess prognosis following curative surgery for gastric cancer. The objective of the current study was to evaluate the performance of the Gastric Cancer Collaborative Group nomograms developed in 2014 by Kim et al., using a cohort of patients from a 10-year single institution experience in gastric cancer management.

PATIENTS AND METHODS

We retrospectively reviewed patients who underwent curative-intent surgery for histologically confirmed gastric cancer at First Surgical Clinic of Padua University Hospital (Italy) from January 2010 to May 2020. Univariable and multivariable Cox proportional hazard models were employed to assess the effect of the variables of interest on mortality and recurrence. Multivariable analysis was performed by considering the variables included in the Gastric Cancer Collaborative Group nomograms in order to validate them. The performance of the nomograms was evaluated using Harrell's C-index and calibration plots.

RESULTS

Overall, 168 patients were included, with a median follow-up of 20.1 months. On multivariable analysis, tumor location, lymph node ratio, and pathological T stage were associated with recurrence; age, tumor location, lymph node ratio, and pT stage were associated with OS (overall survival). The nomograms had good discriminatory capability to classify both OS (C-index: 0.75) and DFS (disease-free survival) (C-index 0.72). The corrected C-Index for DFS based on the AJCC staging system revealed better prediction (C-Index 0.75), while the corrected C-Index for OS had worse discrimination ability compared with the current nomogram (C-Index 0.72).

CONCLUSIONS

The Gastric Cancer Collaborative Group nomograms demonstrated good performances in terms of prediction of both OS and DFS on external validation. The two nomograms are easy to apply, and variables included are widely available to most facilities.

POS1192 BEHAVIOR AND FEELINGS OF PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS DURING LOCKDOWN MEASURES FOR THE COVID-19 OUTBREAK

Background:

COVID-19 is a systemic viral disease currently spreading as a pandemic. A more severe course and prognosis of COVID-19 in systemic lupus erythematosus (SLE) and vasculitis has been reported (1).

Several papers have focused on the concerns, healthcare-related behaviors and psychological impact of COVID-19 pandemic among patients with rheumatic diseases, and specifically on SLE patients, showing a trend towards remarkable psychological distress (2-4). To date, no investigation on the psychological effects of quarantine strategy on SLE patients has been carried out.

Objectives:

To investigate the psychological impact of the lockdown measures adopted in Italy to contrasting the COVID-19 outbreak, on patients with SLE as compared to the general population.

Methods:

Patients affected by SLE were given an online questionnaire focused on psychological impact and self-perception during the lockdown measures contrasting the COVID-19 outbreak. The survey was focused on COVID-19 concerns, emotional impact, self-perception and changes in daily living activities and relationships. Results were compared with those of PRESTO (imPact of quaRantine mEasures againST cOvid19) project, an Italian survey, which used the same questionnaire, directed to the general population, with or without chronic diseases. A propensity matching procedure has been applied to LEPRE (Lupus Erythematosus PRESTO project) cases and the PRESTO responders with a ratio of 2 versus 1.

Results:

64 patients and 1114 unselected people completed the survey. After the matching procedure, patients were compared to 128 matched adults. Missing data were below 6%. The median age among patients was 43 years (I-III interquartile range 35-54.5), 88% were female and 100% Caucasian. The SLE subjects live mainly in detached houses (38/64 vs 348/1114, p<0.0001), having access to a private garden (52/64 vs 625/1112, p<0.0001) and also owning a pet (43/64 vs 508/1114, p<0.001), in comparison with the PRESTO sample living mainly in flats. The psychological impact measured by IES-R, GHQ.12, and CEDS scores were not statistically different between patients and the general population, such as globally COVID-19 concerns and feelings. However, patients perceived more difficulty to find some free time and enjoy it (13/60 vs 48/121, p=0.01) and to be able to solve own problems (47/61 vs 71/120, p=0.02). On the contrary, patients felt more able to cope with the problem and less sad or depressed in comparison with the PRESTO group (17/61 vs 13/120, p=0.003). Moreover, patients missed playing sports/exercise less than general population (12/63 vs 46/128, p=0.02), while they felt more the distance from family and relatives (45/63 vs 42/86, p<0.0001).

Conclusion:

the COVID-19 pandemic didn’t unveil a greater psychological fragility of people living with SLE than the others. By contrast, a coping strategy, including the role of the family and the lifestyle, contributes to resilience of SLE in difficult scenarios such as those presented by the pandemic.

Feasibility and reproducibility of right ventricle stress echocardiography and its capability to assess the right ventricle contractile reserve of patient with at least trivial tricuspid regurgitation

Funding Acknowledgements

Type of funding sources: None.

BACKGROUND. Stress echocardiography (SE) is widely used for the assessment of left ventricular (LV) function, diagnostic and prognostic stratification of patients with coronary artery disease and for assessment of mitral and aortic valve disease. However, the assessment of the right ventricle (RV) in general, and in particular in regard to the contractile reserve of the RV in patients with tricuspid valve (TV) disease is an area that has not been previously explored in adult patients. The physiology and function of the RV is different than that of the LV and the use of SE provides the possibility to test both systolic and diastolic function of the RV in response to increased loading conditions. This can potentially be used to assess the RV function prior to surgery  and to predict which subset of patients may benefit from intervention on the TV before the RV displays signs of failure

PURPOSE. We therefore propose a study to investigate the potential use of SE for the assessment of RV function in adult patients. The aim is to evaluate the feasibility of RV SE in any patients with more than trivial tricuspid regurgitation (TR) and to assess the presence and degree of RV contractile reserve.

METHODS. We enrolled 81 patients undergoing a phisical or dobutamine SE for CV risk stratification or chest pain. Inclusion criteria were age≥ 18 years, normal baseline RV function (FAC&gt; 35%, TAPSE&gt; 16 mm). Exclusion criteria were presence of RV dysfunction, pulmonary stress hypertension, positive stress test for left myocardial ischemia, presence of moderate or severe valvular disease, grade III or higher diastolic dysfunction at baseline, severe respiratory, renal or hepatic dysfunction. We evaluated the average values of TAPSE, fractional area change (FAC), S wave, sPAP (pulmonary systolic blood pressure), RV strain during baseline and at the peak of the effort. We also assessed the reproducibility of these measurement between two different expert operators (blind analysis).

RESULTS. We were able to measure the RV parameters both during baseline and at the peak of the effort in all patients, demonstrating an excellent feasibility. Differences in parameters collected at baseline and at peak were assessed using paired Wilcoxon signed rank test. All variables showed a statistical significant increase (p &lt; 0.001) at peak compared to the baseline. Average percentage increases at peak were 31.1% for TAPSE, 24,8% for FAC, 50,6% for S wave, 55,2% for PAPS and 39.8 % for RV strain. Bland-Altman method was used to evaluate the agreement between measurements collected by two separate operators and it showed  good Intraclass Correlation Coefficients  (Figure).

CONCLUSIONS. RV SE proved to be feasible and showed little inter-operator variability  in patients with at least trivial TR. It provided valuable informations about RV contractile  reserve that may help stratifying the risk of RV failure in patients undergoing TV surgery.

Predictors of death and heart transplantation in biopsy-proven myocarditis: a machine-learning approach

Background

Risk stratification for death and heart transplantation (HTx) in myocarditis is complex. A random forest (RF) is a tree-based machine learning technique (MLT) which is being increasingly used for clinical data analysis; it allows the detection of complex relationships between the outcome of interest and the covariates, overcoming the limits of traditional statistical analysis (i.e. regression approaches). Purpose To assess the potential role of clinical and diagnostic features at presentation as predictors of death and HTx in biopsy (Bx)-proven myocarditis using RF. Methods From January 1993 to August 2019, we consecutively enrolled 357 patients with Bx-proven myocarditis (65% male, median age 39 years, interquartile range (IQR) 26–51). An RF approach for survival data was used. Variables included in the analysis were: histology type by Bx, NYHA, type of presentation (infarct-like, arrhythmia, heart failure), viral genome detection on Bx, serum antiheart (AHA), antiintercalated disk (AIDA), anticardiac endothelial cells (AECA), antinuclear (ANA) autoantibodies, immunosuppressive therapy, cardiac catheterisation (left ventricular enddiastolic volume (LVEDV), mean capillary wedge pressure, right and left ventricular enddiastolic pressure) and 2-D echocardiographic measures (LVEDV, left ventricular ejection fraction (LVEF) at presentation and at follow-up, right ventricular fractional area change (FAC%), right ventricular diastolic area). Results The median follow-up time was of 1352 days (IQR 423.25–2535.75). At the end of follow-up, 42 patients were dead or transplanted. The 1-year, 5-year, and 10-year survival probabilities were of 0.928, 0.854, and 0.817, respectively. The most relevant predictors of death or HTx identified by the RF algorithm (according to the variable importance measure) were histological type, NYHA, clinical presentation, LVEF, and FAC%. Among the circulating auto-antibodies AECA were found to be the most important. Histological type was the strongest predictor of death/HT (100% relative importance, (RI)), giant cell myocarditis having a lower survival probability compared to other types. The next stronger predictors were advanced (III-IV) NYHA and heart failure presentation with lower survival probabilities (90% and 84% RI respectively). AECA-positive patients had lower survival probability compared to AECA negative ones (20% RI). The RF algorithm revealed an excellent predictive performance in the correct identification of all alive patients, with only 5 dead patients being misclassified (balanced accuracy 94%).

Conclusions

Autoimmune features, i.e Giant cell myocarditis and AECA, as well as severity of heart failure and of left ventricular disfunction at presentation were the strongest predictors of dismal prognosis. Our RF approach provides a new automated powerful tool for accurate risk stratification for death/HTx in Bx-proven myocarditis.

Knowledge of stroke and attitude to activate emergency medical services: a cross-sectional study

Introduction

Acute brain stroke is one of the leading causes of death in the world. Translating knowledge of stroke warning signs into appropriate actions is critical to decrease prehospital delay, meaning that the population has a key role in reducing the hospitalization time of affected people.

Objectives

The aim is to understand in which percentage adults (318, without healthcare formation) would react properly by calling emergency medical services (EMS) when presented with hypothetical stroke-related scenarios and how the knowledge of warning signs is related to different factors.

Methods

a population-based online survey was carried out in a random sample of Italian adults in June-July 2019. The STAT (Stroke Action Test) questionnaire included 21 close-ended questions focused on stroke symptoms. The prevalence and distribution of stroke knowledge was examined.

Results

445 subjects were enrolled; the mean age was 36 years. The average score was 10,9/21, and only 21% had an optimal performance. Higher scores are associated with female gender and older age (p &lt; 0,01). When a situation described a single stroke sign, only the 15% recognized the importance to call EMS. The sign/symptom mainly recognized (57%) was “trouble speaking”.

Conclusions

this study provides data describing stroke knowledge among Italian adults; despite its limitations, the study shows that people hesitate to call EMS when stroke signs and symptoms are presented. The knowledge of stroke signs/symptoms remains lower than the heart attack ones. As expected, it would be 'useful to give proper information and training on stroke signs/symptoms' but also it is fundamental to emphasize that stroke is a medical emergency and needs a fast hospital admission.

Key messages

There is a lack of knowledge in stroke emergency shall raise community awareness about the need of education campaigns. It is important to improve stroke's signs and symptoms in order to have better prognosis.

Interventions aimed at lowering risk of falling at home in Parkinson's disease: a literature review

Background

Falls are the most frequent domestic accidents and their impact on subjects' quality of life, healthcare system and potentially serious complications, make their prevention fundamental. 80% of patients with Parkinson's disease fall in their homes, therefore the prevention of falls becomes a priority in caring for these patients. The aim of the study is to identify the evidence relating to home falls prevention interventions in patients with Parkinson's disease.

Methods

A literature review was performed considering articles published between 2000 and 2017 and indexed in PubMed, Cinhal and Cochrane Library. 655 articles were identified and 28 selected and considered for review.

Results

Four macro types of intervention have been identified: environmental and educational interventions, through the preparation of aids, lighting systems, room adaptation, adequate footwear and involvement of caregivers; physical and rehabilitative interventions, through programs of Qigong Baduanjin, Hi-Balance, Tai-Chi, Ai-Chi, vestibular rehabilitation and exercises marked by the metronome; pharmacological interventions, through a continuous infusion system of Rivastigmine or Levodopa; alternative therapies such as vitamin C and Macuna Pruriens.

Conclusions

The available literature points out the effectiveness of multiple interventions in reducing the risk of falling at home for Parkinson's disease patients. To ensure these interventions, a multidisciplinary team management is needed. This approach allows an improvement in the management of the Parkinsonian patient, promoting the maintenance of health and quality of life, preventing complications and optimizing subject's residual abilities and promoting caregivers' involvement.

Key messages

The literature points out the effectiveness of multiple interventions in reducing the risk of falling at home for Parkinson's disease patients. Four macro types of intervention have been identified: environmental and educational, physical and rehabilitative interventions, pharmacological and alternative therapies.

Nursing care in early extubation of cardiosurgical patient: a literature review

Introduction

Recent studies show that mechanical ventilation (MV) is necessary in only 5-10% of cardiosurgical patients. Thus, this finding denies the theory arguing that a prolonged period of MV (24 hours to 7 days) reduces the risk of complications. Based on these considerations, strategies have developed, i.e. the Fast Track (FT), with the aim of encouraging early extubation (1 to 8 hours after surgery). The objectives of this review are: to verify the effectiveness of FT in terms of reducing post-operative complications, mortality and costs, to analyse the operating procedures and inclusion criteria of each protocol and to outline nursing care in the whole process.

Methods

Literature search was performed in Cochrane, PubMed, and CINAHL databases. No limits have been applied on study design and publication timespan. Population included adult patients who underwent cardiac surgery with admission to an intensive care unit and were mechanically ventilated.

Results

16 articles (including 8 RCT) have been selected. The protocols require that nurses, based on specific parameters, assess the possibility of weaning from sedation and early extubation according to standardised practices. Early extubation decreases the risk of MV-related complications by decreasing hospitalization lenght and thus total costs by at least 3%. No significant differences have been found between FT and standard of care regarding postoperative complications and mortality.

Conclusions

Taking into account both the proven applicability, safety and efficacy of FT protocols and their high heterogeneity in published studies, that prevent their comparison, further research is needed to identify a reliable algorithm for early extubation based on pre-operative, intraoperative and postoperative data.

Key messages

Early extubation decreases the risk of MV-related complications by decreasing hospitalization lenght and thus total costs by at least 3%. Recent studies show that mechanical ventilation (MV) is necessary in only 5-10% of cardiosurgical patients.

Perception of end-of-life decisions by healthcare professionals in home palliative care and hospice

Background

Home care and hospices are gaining higher importance in providing end-of-life care. The main aim of this study is to investigate clinical decisions of healthcare professionals in north-eastern home-care services and hospices caring for patients in their end-of-life. Moreover, the study aims to study nurses' and physicians' opinions on palliative care.

Methods

A questionnaire was administered to healthcare personnel in 5 homecare services and 2 hospices in a regional health service trust in north-eastern Italy. The questionnaire is made of three parts: the first deals with clinical decisions for the last patient who died, the second investigates opinions on terminal care, while the last collect data on participants.

Results

42 subjects have been enrolled, most of them are nurses, 64,1% without bioethics training and 53,8% without palliative care training. All the End- of-Life Decisions (DEL) were “non-treatment” decisions. None of the participants discussed the potential life-shortening effect with the patient. The involvement of patients' relatives in terminal care was meaningful for 86% of the professionals. The participants reported they usually discuss terminal issues only when patients or relatives ask for them, but palliative care seems to be the most discussed care-related topic.

Conclusions

Comparison with previous studies can't be performed because of the small number of participants. DEL were exclusively “non-treatment”. We found relevant data about options of shortening life, which was not discussed at all. Mainly only the professionals who give great importance to patient's religious beliefs discussed spiritual themes with them. Finally, the professionals trained in palliative care were more comfortable starting to talk to patients about the possibility of receiving palliative care.

Key messages

This study investigates clinical decisions taken by professionals in home-care and hospices in terminal ill patients care and professionals ‘opinions on palliative care. Communication on palliative care (PC) has been widely investigated: professionals trained in PC were more comfortable starting to talk to patients about the possibility of receiving PC.

End-of-life decisions and appropriateness of care in intensive care: a cross-sectional, pilot study

In Intensive Care Units (ICUs) patients can experience severe organ failures. In several cases, failures can be incurable, making many of the treatments inappropriate, according to ethical principles. Based on the current legislation, in ICUs, clinicians proceed to limit life support care in most of the cases described. Despite this, some studies report that in many cases the care provided is inappropriate for the prognosis. The study aims at investigating the type and frequency of healthcare personnel's End of Life Decisions (DEL) and the point of view of patients' family, contributing to the debate.

A non-interventional cross-sectional pilot study was conducted in 3 ICUs in North-Eastern Italy. Two questionnaires were administered: the first investigates DEL and the perception of nurses and physicians regarding the inadequacy of care provided to patients (from the ELDY study), the second focuses on the family's opinions. Data are expressed by frequencies, percentages, means and standard deviations.

In line with most of previous studies, cases identified as DEL are all related to non-treatment decisions (n = 20, 74%), 44% of these are related to having stopped or not started treatments already knowing the possibility of anticipating the end of life of the patient, while 27% had the precise intention of shortening life. The situation has been discussed with patient's relatives only in two cases. The cause of increased inappropriateness (87%) was the perception that other patients would benefit more from intensive care than the patient in charge, and 40% of the healthcare personnel reported that similar situations occur very frequently.

The restriction of treatment has been confirmed as the most frequent DEL, and interruption being more frequent than non-implementation. Given the high rate of inappropriate care, it could be effective to follow adequate guidelines in the management of the DEL and discuss strategies within the team and with patients' family.

Key messages

When severe organ failures are incurable, in ICUs clinicians proceed to limit life support to the patient in charge. Despite this, in many cases the care provided is inappropriate for the prognosis. Given the high rate of inappropriate care, it could be effective to follow adequate guidelines in the management of the DEL and discuss strategies within the team and with patients’ family.

Care Manager nurse for chronic patients in primary care: a literature review

Background

The reorganization of home care provides nurses the opportunity to move to a role of “Care Manager”, affording a more effective management of chronic patients. This study aims to investigate whether the introduction of this new nursing role improved care related outcomes in people with one or more chronic conditions in primary care setting.

Methods

Articles considered for this review had to assess the outcomes obtained from outpatient care and home care in which the care manager nurse had been involved. Literature search was performed in PubMed, Cinahl, Scopus, Cochrane, and Google Scholar.

Results

20 studies have been selected. Care manager was introduced mainly into the American healthcare systems (80%) and only partly in the European ones (20%). Nurse provided outpatient care (95%) and home care (75%) dealing with the development of the care plan, therapeutic education and proactive prevention. The interventions were based on three fundamental principles of the Chronic Care Model: care teams, self-care support, computerized information system. The health outcomes achieved include: reduction of health care costs, hospital admissions and mortality rates; improvements of disease-specific clinical parameters and quality of life, and an excellent level of satisfaction on patients' and healthcare professionals' side (perceived quality of care).

Conclusions

The literature shows that nursing interventions carried out by the care manager in collaboration with other primary care professionals provided positive results in many ways.

Key messages

The reorganization of home care provides nurses the opportunity to take the role of “Care Manager”. This figure could afford a more effective management of chronic patients.

Nurse provided outpatient care (95%) and home care (75%) dealing with the development of the care plan, therapeutic education and proactive prevention. These interventions led to positive results.

Association between air pollution and Pediatric Intensive Care Units hospitalization rates

Background

In the last years air pollution has been linked to an increased risk of several children respiratory pathologies, especially low respiratory tract infections. In more severe cases, the child could be hospitalized in Pediatric Intensive Care Unit (PICU). The present study aims to evaluate the association between the exposure to air pollution and (i) PICU admissions and (ii) hospitalization rates among children with a previous PICU admission.

Methods

PICU admissions due to respiratory diseases were collected from 2010 to 2019 in Padua hospital (Italy) based on a large clinical Italian register. Furthermore, for subjects admitted in 2013, all subsequent hospitalizations have been tracked until 2019 from hospital discharge records. Environmental data were obtained from monitoring stations located within 20 km from the children residence. A conditional logistic regression based on a time-stratified case-crossover design will be performed to evaluate the association between hospital admissions and NO2, PM2.5 and PM10 in aerodynamic diameter.

Results

The registry contains data about more than 30000 PICU admissions, of which around 30 % are of children under one year of age. An increased prevalence for respiratory diseases' admissions, from 18% in 2010 to 24% in 2019 can be observed. More than 400 children were admitted to Padua's PICU in 2013. In the following years, all these subjects experienced at least one hospitalization (median 2, [IQR 1-5]) for more than 2000 hospital admissions from 2014 up to 2019.

Conclusions

Exposure of infants to air pollution could lead to more severe outcome as hospitalization as a result of a vulnerable lung condition that eases virus infections. This condition identifies a particularly frail population. With this approach, an association between air pollution and PICU admissions could be investigated in order to adopt public health policies aimed at safeguarding this frail population.

Key messages

The study would detect an association between air pollution and hospital admissions as severe outcomes in infants and children. Furthermore, this is the first study that would assess if there is an association between these two factors in more frail subjects already hospitalized in a Pediatric Intensive Care Unit.

Caregivers' and relatives' grief in intensive care unit: a literature review on nursing practices

Introduction

The sudden and unexpected nature, which often characterizes death in intensive care, complicates the processing of the loss by relatives and caregivers increasing the risk of complicated grief (CG). Due to the high social impact and long-term consequences on the quality of life of relatives and caregivers, intensive care nurses should ensure evidence-based grief support interventions. This review aims to identify nursing interventions for the management of the bereavement of relatives and caregivers and to assess their effectiveness, relatives' and caregivers' satisfaction and prevention of CG.

Methods

Research was performed in CINAHL, PubMed, Psycinfo and Scopus databases with no limits on study design and publication timespan. The population included relatives or caregivers of patients died in intensive care unit.

Results

14 studies met inclusion criteria. Two studies show that the communication of the bad news through dialogue between the team and relatives/caregivers can reduce, in the latter, the levels of anxiety and depression and the incidence of post-traumatic stress disorder. The quality study by Kentish-Barnes et al. (2017) shows that subjects perceived support in receiving a letter of condolence, but the RCT of the same author concludes that those who received the letter were more exposed to the risk of CG. Four studies claim that follow-up meetings facilitate the process of adaptation to loss by providing relatives/caregivers the opportunity to clarify the circumstances of death. Finally, two studies report that the events of commemoration arouse positive emotions in family members.

Conclusions

The review process has identified only a small number of evidences on the effectiveness of nursing interventions, preventing the possibility of providing recommendations or guidelines. Further research is needed and it should consist of RCTs of high methodological quality.

Key messages

Due to the long-term consequences of the sudden death on the quality of life of relatives and caregivers, intensive care nurses should ensure evidence-based grief support interventions. The review process has identified only a small number of evidences on the effectiveness of nursing interventions, preventing the possibility of providing recommendations or guidelines.

Healthy ageing: the natural consequences of good nutrition-a conference report

Many countries are witnessing a marked increase in longevity and with this increased lifespan and the desire for healthy ageing, many, however, suffer from the opposite including mental and physical deterioration, lost productivity and quality of life, and increased medical costs. While adequate nutrition is fundamental for good health, it remains unclear what impact various dietary interventions may have on prolonging good quality of life. Studies which span age, geography and income all suggest that access to quality foods, host immunity and response to inflammation/infections, impaired senses (i.e., sight, taste, smell) or mobility are all factors which can limit intake or increase the body's need for specific micronutrients. New clinical studies of healthy ageing are needed and quantitative biomarkers are an essential component, particularly tools which can measure improvements in physiological integrity throughout life, thought to be a primary contributor to a long and productive life (a healthy "lifespan"). A framework for progress has recently been proposed in a WHO report which takes a broad, person-centered focus on healthy ageing, emphasizing the need to better understand an individual's intrinsic capacity, their functional abilities at various life stages, and the impact by mental, and physical health, and the environments they inhabit.

Risk of atrial fibrillation among bisphosphonate users: a multicenter, population-based, Italian study

Bisphosphonate treatment is used to prevent bone fractures. A controversial association of bisphosphonate use and risk of atrial fibrillation has been reported. In our study, current alendronate users were associated with a higher risk of atrial fibrillation as compared with those who had stopped bisphosphonate (BP) therapy for more than 1 year.

INTRODUCTION

Bisphosphonates are widely used to prevent bone fractures. Controversial findings regarding the association between bisphosphonate use and the risk of atrial fibrillation (AF) have been reported. The aim of this study was to evaluate the risk of AF in association with BP exposure.

METHODS

We performed a nested case-control study using the databases of drug-dispensing and hospital discharge diagnoses from five Italian regions. The data cover a period ranging from July 1, 2003 to December 31, 2006. The study population comprised new users of bisphosphonates aged 55 years and older. Patients were followed from the first BP prescription until an occurrence of an AF diagnosis (index date, i.e., ID), cancer, death, or the end of the study period, whichever came first. For the risk estimation, any AF case was matched by age and sex to up to 10 controls from the same source population. A conditional logistic regression was performed to obtain the odds ratio with 95% confidence intervals (CI). The BP exposure was classified into current (<90 days prior to ID), recent (91-180), past (181-364), and distant past (≥365) use, with the latter category being used as a reference point. A subgroup analysis by individual BP was then carried out.

RESULTS

In comparison with distant past users of BP, current users of BP showed an almost twofold increased risk of AF: odds ratio (OR) = 1.78 and 95% CI = 1.46-2.16. Specifically, alendronate users were mostly associated with AF as compared with distant past use of BP (OR, 1.97; 95% CI, 1.59-2.43).

CONCLUSION

In our nested case-control study, current users of BP are associated with a higher risk of atrial fibrillation as compared with those who had stopped BP treatment for more than 1 year.

Effectiveness of oral chlorhexidine on nosocomial pneumonia, causative micro-organisms and mortality in critically ill patients: a systematic review and meta-analysis

We carried out a systematic review and meta-analysis of randomized trials to explore the effectiveness of oral chlorhexidine on nosocomial pneumonia, causative bacteria, and mortality. PubMed, Embase, and the Cochrane Register of Controlled Trials were searched for randomized trials in critically ill patients receiving oral chlorhexidine. Odds ratios (OR) were pooled with the random effects model. Twenty-two randomized trials including 4277 patients were identified. Chlorhexidine significantly reduced the incidence of nosocomial pneumonia (OR 0.66; 95% confidence interval [CI] 0.51-0.85) and ventilator-associated pneumonia (OR 0.68, 95% CI 0.53-0.87). There was a significant reduction of nosocomial pneumonia due to both Gram-positive (OR 0.41; 95% CI 0.19-0.85) and Gram-negative (OR 0.68; 95% CI 0.51-0.90) bacteria, but only pneumonia due to "normal" flora (OR 0.51; 95% CI 0.33-0.80). The subgroup analysis revealed a significant benefit of chlorhexidine on nosocomial pneumonia in surgical patients only (OR 0.52; 95% CI 0.33-0.82). Mortality was not affected. This review indicates that in critically ill, mainly surgical, patients, oral chlorhexidine reduces nosocomial pneumonia, ventilator-associated pneumonia, nosocomial pneumonia due to Gram-positive and Gram-negative bacteria, and due to "normal" flora, without affecting mortality. Further studies should explore the efficacy of oral chlorhexidine in non-surgical critically ill population.

A single-centre, before-after study of the short- and long-term efficacy of Narivent(®) in the treatment of nasal congestion

OBJECTIVE

Nasal congestion is a common symptom in allergic and nonallergic rhinitis, rhinosinusitis and nasal polyposis. The present study evaluated the clinical effectiveness of Narivent(®), an osmotically-acting medical device with anti oedematous and anti-inflammatory effects, in nasal congestion.

METHODS

A single-centre, prospective study with a pre- post design and consecutive patient enrolment was conducted in an Italian otolaryngology department. Patients with persistent nasal congestion were allocated to treatment groups as follows: group 1 (n = 36) treated for 7 days; group 2 (n = 56) treated for 30 days. In each group, patients received two puffs of Narivent(®) into each nostril twice daily. Symptom severity was assessed subjectively on a 0-10 visual analogue scale, and objectively by the presence/absence of signs and symptoms. Differences in subjective and objective severity measures before and after treatment were compared using Wilcoxon's signed rank test.

RESULTS

All symptoms and objective scores improved after treatment with Narivent(®) for 7 or 30 days and no adverse effects were reported by the patients in either group.

CONCLUSION

Narivent(®) appears to be efficacious in treating nasal congestion over a 7- or a 30-day period.

Assessing the risk of osteonecrosis of the jaw due to bisphosphonate therapy in the secondary prevention of osteoporotic fractures

SUMMARY

There is evidence that the use oral bisphosphonates can lead to osteronecrosis of the jaws (ONJ). Although the occurrence of ONJ appears rare among oral bisphosphonates (BPs) users, it is important to know that it exists and can be opportunely minimized.

INTRODUCTION

The purpose of this study is to evaluate the association between BPs prescribed for the secondary prevention of osteoporotic fractures and the occurrence of ONJ.

METHODS

An Italian record linkage claims database with a target population of around 18 million individuals (6 million over 55 years of age) constituted the data source. We conducted a nested case-control study within a cohort of individuals aged 55+ years old, who were discharged from hospitals with a primary diagnosis of incident osteoporotic fracture. The date related to the discharge diagnosis of ONJ was the index date. Conditional logistic regression for matched data was fitted to estimate the odds ratio (OR) along with 95 % confidence intervals (95 % CI) for the likely association between use of BPs and the risk of ONJ.

RESULTS

Any one of the 61 ascertained cases of ONJ (incidence rate, 36.6 per 100,000 person-years) was matched to 20 controls for a total of 1120 controls. When the exposure to BPs was modeled according to recency (i.e., exposure time window prior to the index date) of use, the adjusted OR (95 % CI) for current users was 2.8 (1.3-5.9) against never users. The cumulative use of BPs has shown to increase the incidence of ONJ among patients with primary osteoporotic fractures, although not statistically significant risk has been observed.

CONCLUSIONS

Although the risk of BP-related ONJ appears low in non-oncological indications, it is important to be aware that it exists and to know how it may be predicted and possibly minimized.

Age limit for infiltration anaesthesia for the conservative treatment of mandibular first molars. A clinical study on a paediatric population

AIM

The aims of this study were to assess the age limit for infiltration anaesthesia as an effective technique in treating carious lesions of first permanent molars in the paediatric age and if differences exist between males and females.

MATERIALS AND METHODS

A total of 51 teeth from 48 different patients aged between 6 and 14 years were included in the study. The anaesthetic solution used was 1.8 ml of 2% mepivacaine with 1:100000 epinephrine. The effectiveness of anaesthesia was assessed by electrical pulp test after 3, 5, 7 and 10 minutes.

RESULTS

In 56.9% of the treated cases a single mandibular infiltration was sufficient to induce complete pulpal anaesthesia of the tooth to be treated. Under 10 years of age, the infiltration technique was effective in 85.2% of cases. The success rate of anaesthesia also decreased significantly and not linearly in function of age. The success of infiltration anaesthesia was not related to gender.

CONCLUSION

Mandibular infiltration anaesthesia is a successful technique for most patients under 10 years (success rate: 85.2%) especially for the younger ones, with no differences between males and females. After this age that success rate dramatically drops.

Risk posed to children by stationery items in the upper airways

AIM

The aim of the present study is to characterize the risk of complications and prolonged hospitalization due to stationery items according to age and gender of patients, FB characteristics and foreign body (FB) location, circumstances of the accident, as emerging from the ESFBI study.

METHODS

A retrospective study in major hospitals of 19 European countries was realized on children aged 0-14 having inhaled/aspired or ingested a stationery item. In the years 2000-2003 a total of 2094 FB injuries occurred in children aged 0-14 years. The characteristics of the child, the FB consistency and the occurrence of complications were analyzed.

RESULTS

Among FB injuries, 62 (3%) were due to a stationery item: 32 were due to objects insertion in the ears while 30 occurred in the upper and lower respiratory tract. Objects most frequently involved are parts of pens in children younger than 3 years and eraser in older. 39% of children needed hospitalization. The most documented complication was inflammation of external ear. Almost 24% of injuries happened under adults' supervision.

CONCLUSION

Injuries are events that in many cases can be prevented with appropriate strategies. Passive environmental strategies, including product modification by manufacturers, are the most effective. Our study testifies that stationary is involved in a non negligible percentage of FB injuries. This results confirm the fact that when passive preventive strategies are not practical, active strategies that promote behaviour change are necessary and information about this issue should be included in all visits to family pediatricians.
